Abstract Complexes [Co(tren)(Tsal)]ClO4·H2O 1 and [Ni(pn)(py)2(NCS)2] 2, (tren = tris(2-aminoethyl)amine, Tsal = thiosalicylate ion, pn = 1, 2-diamino propane and py = pyridine) have been synthesized and structurally characterized. Both complexes crystallize in the monoclinic space group C2/c with a = 21.3340(6), b = 11.7754(2), c = 14.8076(5) Å, β = 100.3831(10)°, Z = 8 (1), and a = 7.2573(8), b = 17.8810(11), c = 15.2681(12) Å, β = 101.170(2)°, Z = 4 (2). The metal atoms in both cases have distorted octahedral geometry. In 1, the tren ligand is quadridentate and Tsal is bidentate chelate. In 2, the pn ligand forms a bidentate chelate with the NCS ligands in trans positions. Complex 1 is diamagnetic whereas 2 shows paramagnetism with a magnetic moment of 3.10 B. M.
